Methods for producing a canola variety comprise crossing canola variety 19GN2390G with another canola plant. Methods for producing a canola plant containing in its genetic material one or more traits introgressed into 19GN2390G through backcross conversion and/or transformation, and to the canola seed, plant and plant part produced thereby are described. Canola variety, the seed, the plant produced from the seed, plant parts and variants, mutants, and minor modifications of canola variety are disclosed.

BACKGROUND

The present discovery relates to a novel rapeseed variety designated19GN2390G which is the result of years of careful breeding andselection. The variety is of high quality and possesses a relatively lowlevel of erucic acid in the vegetable oil component and a relatively lowlevel of glucosinolate content in the meal component to be termed“canola” in accordance with the terminology commonly used by plantscientists.

The goal of plant breeding is to combine in a single variety or hybridvarious desirable traits. For field crops, these traits may includeresistance to diseases and insects, tolerance to heat and drought,reducing the time to crop maturity, greater yield, and better agronomicquality. With mechanical harvesting of many crops, uniformity of plantcharacteristics such as germination and stand establishment, growthrate, maturity, and plant and pod height should be maintained.Traditional plant breeding is an important tool in developing new andimproved commercial crops such as canola.

SUMMARY

A novel Brassica napus variety designated 19GN2390G is provided. Seedsof the 19GN2390G variety, plants of the 19GN2390G variety, and methodsfor producing a canola plant by crossing the 19GN2390G variety withitself or another canola plant (whether by use of male sterility or openpollination), and methods for producing a canola plant containing in itsgenetic material one or more transgenes, and to transgenic plantsproduced by that method are provided. Canola seeds and plants producedby crossing the variety 19GN2390G with another line.

The 19GN2390G plant may further comprise a cytoplasmic or nuclear factorcapable of conferring male sterility or otherwise preventingself-pollination, such as by self-incompatibility. Parts of the canolaplants disclosed herein are also provided, for example, pollen or ovulesobtained from the plant.

Compositions are provided comprising a seed of canola line 19GN2390Gcomprised in plant seed growth media. In certain embodiments, the plantseed growth media is a soil or synthetic cultivation medium. In specificembodiments, the growth medium may be comprised in a container or may,for example, be soil in a field.

Canola line 19GN2390G is provided comprising an added heritable trait.The heritable trait may be a genetic locus that is a dominant orrecessive allele. In certain embodiments, the genetic locus conferstraits such as, for example, male sterility, herbicide tolerance orresistance, insect resistance, resistance to bacterial, fungal, nematodeor viral disease, and altered or modified fatty acid, phytate, proteinor carbohydrate metabolism. The genetic locus may be a naturallyoccurring canola gene introduced into the genome of a parent of thevariety by backcrossing, a natural or induced mutation or modification,or a transgene introduced through genetic transformation techniques.When introduced through transformation, a genetic locus may comprise oneor more transgenes integrated at a single chromosomal location.

Canola line 19GN2390G is provided, wherein a cytoplasmically-inheritedtrait has been introduced into the plant. An exemplarycytoplasmically-inherited trait is the male sterility trait.Cytoplasmic-male sterility (CMS) is a pollen abortion phenomenondetermined by the interaction between the genes in the cytoplasm and thenucleus. Alteration in the mitochondrial genome and the lack of restorergenes in the nucleus will lead to pollen abortion. With either a normalcytoplasm or the presence of restorer gene(s) in the nucleus, the plantwill produce pollen normally. A CMS plant can be pollinated by amaintainer version of the same variety, which has a normal cytoplasm butlacks the restorer gene(s) in the nucleus, and continues to be malesterile in the next generation. The male fertility of a CMS plant can berestored by a restorer version of the same variety, which must have therestorer gene(s) in the nucleus. With the restorer gene(s) in thenucleus, the offspring of the male-sterile plant can produce normalpollen grains and propagate. A cytoplasmically inherited trait may be anaturally occurring canola trait or a trait introduced through genetictransformation techniques.

DETAILED DESCRIPTION

Field crops are bred through techniques that take advantage of theplant's method of pollination. A plant is self-pollinated if pollen fromone flower is transferred to the same or another flower of the sameplant or a genetically identical plant. A plant is sib-pollinated whenindividuals within the same family or line are used for pollination. Aplant is cross-pollinated if the pollen comes from a flower on agenetically different plant from a different family or line. The term“cross-pollination” used herein does not include self-pollination orsib-pollination.

Canola breeding programs utilize techniques such as mass and recurrentselection, backcrossing, pedigree breeding and haploidy.

Recurrent selection is used to improve populations of either self- orcross-pollinating Brassica. Through recurrent selection, a geneticallyvariable population of heterozygous individuals is created byintercrossing several different parents. The best plants are selectedbased on individual superiority, outstanding progeny, and/or excellentcombining ability. The selected plants are intercrossed to produce a newpopulation in which further cycles of selection are continued. Variousrecurrent selection techniques are used to improve quantitativelyinherited traits controlled by numerous genes.

Breeding programs use backcross breeding to transfer genes for a simplyinherited, highly heritable trait into another line that serves as therecurrent parent. The source of the trait to be transferred is calledthe donor parent. After the initial cross, individual plants possessingthe desired trait of the donor parent are selected and are crossed(backcrossed) to the recurrent parent for several generations. Theresulting plant is expected to have the attributes of the recurrentparent and the desirable trait transferred from the donor parent. Thisapproach has been used for breeding disease resistant phenotypes of manyplant species and has been used to transfer low erucic acid and lowglucosinolate content into lines and breeding populations of Brassica.

Pedigree breeding and recurrent selection breeding methods are used todevelop varieties from breeding populations. Pedigree breeding startswith the crossing of two genotypes, each of which may have one or moredesirable characteristics that is lacking in the other or whichcomplements the other. If the two original parents do not provide all ofthe desired characteristics, other sources can be included in thebreeding population. In the pedigree method, superior plants are selfedand selected in successive generations. In the succeeding generationsthe heterozygous condition gives way to homogeneous lines as a result ofself-pollination and selection. Typically, in the pedigree method ofbreeding, five or more generations of selfing and selection arepracticed: F₁ to F₂; F₂ to F₃; F₃ to F₄; F₄ to F₅, etc. For example, twoparents that are believed to possess favorable complementary traits arecrossed to produce an F₁. An F₂ population is produced by selfing one orseveral F₁'s or by intercrossing two F₁'s (i.e., sib mating). Selectionof the best individuals may begin in the F₂ population, and beginning inthe F₃ the best individuals in the best families are selected.Replicated testing of families can begin in the F₄ generation to improvethe effectiveness of selection for traits with low heritability. At anadvanced stage of inbreeding (i.e., F₆ and F₇), the best lines ormixtures of phenotypically similar lines commonly are tested forpotential release as new cultivars. Backcrossing may be used inconjunction with pedigree breeding; for example, a combination ofbackcrossing and pedigree breeding with recurrent selection has beenused to incorporate blackleg resistance into certain cultivars ofBrassica napus.

Blackleg tolerance is measured following the standard proceduredescribed in the Procedures of the Western Canada Canola/RapeseedRecommending Committee (WCC/RRC) Incorporated for the Evaluation andRecommendation for Registration of Canola/Rapeseed Candidate Cultivarsin Western Canada. Blackleg is rated on a scale of 0 to 5: a plant withzero rating is completely immune to disease while a plant with “5”rating is dead due to blackleg infection.

Canola variety “Westar” is included as an entry/control in each blacklegtrial. Tests are considered valid when the mean rating for Westar isgreater than or equal to 2.6 and less than or equal to 4.5. (In yearswhen there is poor disease development in Western Canada the WCC/RRC mayaccept the use of data from trials with a rating for Westar exceeding2.0.)

The ratings are converted to a percentage severity index for each line,and the following scale is used to describe the level of resistance:

Classification Rating (% of Westar) R (Resistant) <30 MR (ModeratelyResistant) 30-49 MS (Moderately Susceptible) 50-69 S (Susceptible) 70-89HS (Highly Susceptible)  90-100

Plants that have been self-pollinated and selected for type for manygenerations become homozygous at almost all gene loci and produce auniform population of true breeding progeny. If desired, double-haploidmethods can also be used to extract homogeneous lines. A cross betweentwo different homozygous lines produces a uniform population of hybridplants that may be heterozygous for many gene loci. A cross of twoplants each heterozygous at a number of gene loci will produce apopulation of hybrid plants that differ genetically and will not beuniform.

The choice of breeding or selection methods depends on the mode of plantreproduction, the heritability of the trait(s) being improved, and thetype of cultivar used commercially, such as F₁ hybrid variety or openpollinated variety. A true breeding homozygous line can also be used asa parental line (inbred line) in a commercial hybrid. If the line isbeing developed as an inbred for use in a hybrid, an appropriatepollination control system should be incorporated in the line.Suitability of an inbred line in a hybrid combination will depend uponthe combining ability (general combining ability or specific combiningability) of the inbred.

Various breeding procedures are also utilized with these breeding andselection methods. The single-seed descent procedure in the strict senserefers to planting a segregating population, harvesting a sample of oneseed per plant, and using the one-seed sample to plant the nextgeneration. When the population has been advanced from the F₂ to thedesired level of inbreeding, the plants from which lines are derivedwill each trace to different F₂ individuals. The number of plants in apopulation declines each generation due to failure of some seeds togerminate or some plants to produce at least one seed. As a result, notall of the F₂ plants originally sampled in the population will berepresented by a progeny when generation advance is completed.

In a multiple-seed procedure, canola breeders commonly harvest one ormore pods from each plant in a population and thresh them together toform a bulk. Part of the bulk is used to plant the next generation andpart is put in reserve. The procedure has been referred to as modifiedsingle-seed descent or the pod-bulk technique. The multiple-seedprocedure has been used to save labor at harvest. It is considerablyfaster to thresh pods with a machine than to remove one seed from eachby hand for the single-seed procedure. The multiple-seed procedure alsomakes it possible to plant the same number of seeds of a population eachgeneration of inbreeding. Enough seeds are harvested to make up forthose plants that did not germinate or produce seed. If desired,doubled-haploid methods can be used to extract homogeneous lines.

Molecular markers, including techniques such as Isozyme Electrophoresis,Restriction Fragment Length Polymorphisms (RFLPs),

Randomly Amplified Polymorphic DNAs (RAPD),

Arbitrarily Primed Polymerase Chain Reaction (AP-PCR),

DNA Amplification Fingerprinting (DAF), Sequence Characterized AmplifiedRegions (SCARs), Amplified Fragment Length Polymorphisms (AFLPs), SimpleSequence Repeats (SSRs) and Single Nucleotide Polymorphisms (SNPs), maybe used in plant breeding methods. One use of molecular markers isQuantitative Trait Loci (QTL) mapping. QTL mapping is the use of markerswhich are known to be closely linked to alleles that have measurableeffects on a quantitative trait. Selection in the breeding process isbased upon the accumulation of markers linked to the positive effectingalleles and/or the elimination of the markers linked to the negativeeffecting alleles in the plant's genome.

Molecular markers can also be used during the breeding process for theselection of qualitative traits. For example, markers closely linked toalleles or markers containing sequences within the actual alleles ofinterest can be used to select plants that contain the alleles ofinterest during a backcrossing breeding program. The markers can also beused to select for the genome of the recurrent parent and against themarkers of the donor parent. Using this procedure can minimize theamount of genome from the donor parent that remains in the selectedplants. It can also be used to reduce the number of crosses back to therecurrent parent needed in a backcrossing program. The use of molecularmarkers in the selection process is often called Genetic Marker EnhancedSelection or Marker Assisted Selection (MAS).

The production of doubled haploids can also be used for the developmentof inbreds in the breeding program. In Brassica napus, microsporeculture technique may be used to produce haploid embryos. The haploidembryos are then regenerated on appropriate media as haploid plantlets,doubling chromosomes of which results in doubled haploid plants. Thiscan be advantageous because the process omits the generations of selfingneeded to obtain a homozygous plant from a heterozygous source.

The development of a canola hybrid in a canola plant breeding programinvolves three steps: (1) the selection of plants from various germplasm pools for initial breeding crosses; (2) the selfing of theselected plants from the breeding crosses for several generations toproduce a series of inbred lines, which, although different from eachother, breed true and are highly uniform; and (3) crossing the selectedinbred lines with different inbred lines to produce the hybrids. Duringthe inbreeding process in canola, the vigor of the lines decreases.Vigor is restored when two different inbred lines are crossed to producethe hybrid. A consequence of the homozygosity and homogeneity of theinbred lines is that the hybrid between a defined pair of inbreds willalways be the same. Once the inbreds that give a superior hybrid havebeen identified, the hybrid seed can be reproduced indefinitely as longas the homogeneity of the inbred parents is maintained.

19GN2390G may also be used to produce a double cross hybrid or athree-way hybrid. A single cross hybrid is produced when two inbredvarieties are crossed to produce the F1 progeny. A double cross hybridis produced from four inbred varieties crossed in pairs (A×B and C×D)and then the two F1 hybrids are crossed again (A×B)×(C×D). A three-waycross hybrid is produced from three inbred varieties where two of theinbred varieties are crossed (A×B) and then the resulting F1 hybrid iscrossed with the third inbred variety (A×B)×C. In each case, pericarptissue from the female parent will be a part of and protect the hybridseed.

Another form of commercial hybrid production involves the use of amixture of male sterile hybrid seed and male pollinator seed. Whenplanted, the resulting male sterile hybrid plants are pollinated by thepollinator plants. This method can be used to produce grain withenhanced quality grain traits, such as high oil. One use of this methodis described in U.S. Pat. Nos. 5,704,160 and 5,706,603.

Molecular data from 19GN2390G may be used in a plant breeding process.Nucleic acids may be isolated from a seed of 19GN2390G or from a plant,plant part, or cell produced by growing a seed of 19GN2390G or from aseed of 19GN2390G with a locus conversion, or from a plant, plant part,or cell of 19GN2390G with a locus conversion. One or more polymorphismsmay be isolated from the nucleic acids. A plant having one or more ofthe identified polymorphisms may be selected and used in a plantbreeding method to produce another plant.

Phenotypic Characteristics of 19GN2390G

Hybrid canola variety 19GN2390G is a single cross canola variety and canbe made by crossing inbreds G00012 and N00655. Locus conversions ofhybrid canola variety 19GN2390G can be made by crossing inbreds G00012and N00655 wherein G00012 and/or N00655 comprise a locus conversion(s).

The canola variety has shown uniformity and stability within the limitsof environmental influence for all the traits as described herein (see,e.g. Table 1). The inbred parents of this canola variety have beenself-pollinated a sufficient number of generations with carefulattention paid to uniformity of plant type to ensure the homozygosityand phenotypic stability necessary for use in commercial hybrid seedproduction. The variety has been increased both by hand and in isolatedfields with continued observation for uniformity. No variant traits havebeen observed or are expected in 19GN2390G.

Hybrid canola variety 19GN2390G can be reproduced by planting seeds ofthe inbred parent varieties, growing the resulting canola plants undercross pollinating conditions, and harvesting the resulting seed usingtechniques familiar to the agricultural arts.

Controlling Self-Pollination

Canola varieties are mainly self-pollinated. A pollination controlsystem and effective transfer of pollen from one parent to the otherprovides an effective method for producing hybrid canola seed andplants. For example, the ogura cytoplasmic male sterility (CMS) system,developed via protoplast fusion between radish (Raphanus sativus) andrapeseed (Brassica napus), is one of the most frequently used methods ofhybrid production. It provides stable expression of the male sterilitytrait and an effective nuclear restorer gene. The OGU INRA restorergene, Rf1 originating from radish has improved versions.

Brassica hybrid varieties can be developed using self-incompatible (SI),cytoplasmic male sterile (CMS) or nuclear male sterile (NMS) Brassicaplants as the female parent such that only cross pollination will occurbetween the hybrid parents.

In one instance, production of F₁ hybrids includes crossing a CMSBrassica female parent with a pollen-producing male Brassica has afertility restorer gene (Rf gene). The presence of an Rf gene means thatthe F₁ generation will not be completely or partially sterile, so thateither self-pollination or cross pollination may occur. Self pollinationof the F₁ generation to produce several subsequent generations verifiesthat a desired trait is heritable and stable and that a new variety hasbeen isolated.

Other sources and refinements of CMS sterility in canola include thePolima cytoplasmic male sterile plant, as well as those of U.S. Pat. No.5,789,566, DNA sequence imparting cytoplasmic male sterility,mitochondrial genome, nuclear genome, mitochondria and plant containingsaid sequence and process for the preparation of hybrids; See U.S. Pat.Nos. 4,658,085, 5,973,233 and 6,229,072.

Hybrid Development

As a result of the advances in sterility systems, lines are developedthat can be used as an open pollinated variety (i.e., a purelinecultivar) and/or as a sterile inbred (female) used in the production ofF₁ hybrid seed. In the latter case, favorable combining ability with arestorer (male) would be desirable.

The development of a canola hybrid generally involves three steps: (1)the selection of plants from various germplasm pools for initialbreeding crosses; (2) generation of inbred lines, such as by selfing ofselected plants from the breeding crosses for several generations toproduce a series of different inbred lines, which breed true and arehighly uniform; and (3) crossing the selected inbred lines withdifferent inbred lines to produce the hybrids.

Combining ability of a line, as well as the performance of the line perse, is a factor in the selection of improved canola lines that may beused as inbreds. Combining ability refers to a line's contribution as aparent when crossed with other lines to form hybrids. The hybrids formedfor the purpose of selecting superior lines are designated test crosses.One way of measuring combining ability is by using breeding values.Breeding values are based on the overall mean of a number of testcrosses. This mean is then adjusted to remove environmental effects andit is adjusted for known genetic relationships among the lines.

Brassica napus canola plants, absent the use of sterility systems, arerecognized to commonly be self-fertile with approximately 70 to 90percent of the seed normally forming as the result of self-pollination.The percentage of cross pollination may be further enhanced whenpopulations of recognized insect pollinators at a given growing site aregreater. Thus open pollination is often used in commercial canolaproduction.

Locus Conversions of Canola Variety 19GN2390G

19GN2390G represents a new base genetic line into which a new locus ortrait may be introduced. Direct transformation and backcrossingrepresent two methods that can be used to accomplish such anintrogression. The term locus conversion is used to designate theproduct of such an introgression.

Backcrossing can be used to improve inbred varieties and a hybridvariety which is made using those inbreds. Backcrossing can be used totransfer a specific desirable trait from one variety, the donor parent,to an inbred called the recurrent parent which has overall goodagronomic characteristics yet that lacks the desirable trait. Thistransfer of the desirable trait into an inbred with overall goodagronomic characteristics can be accomplished by first crossing arecurrent parent to a donor parent (non-recurrent parent). The progenyof this cross is then mated back to the recurrent parent followed byselection in the resultant progeny for the desired trait to betransferred from the non-recurrent parent.

Traits may be used by those of ordinary skill in the art to characterizeprogeny. Traits are commonly evaluated at a significance level, such asa 1%, 5% or 10% significance level, when measured in plants grown in thesame environmental conditions. For example, a locus conversion of19GN2390G may be characterized as having essentially the same phenotypictraits as 19GN2390G. The traits used for comparison may be those traitsshown in any of the tables herein. Molecular markers can also be usedduring the breeding process for the selection of qualitative traits. Forexample, markers can be used to select plants that contain the allelesof interest during a backcrossing breeding program. The markers can alsobe used to select for the genome of the recurrent parent and against thegenome of the donor parent. Using this procedure can minimize the amountof genome from the donor parent that remains in the selected plants.

A locus conversion of 19GN2390G may contain at least 1, 2, 3, 4 or 5locus conversions, and fewer than 15, 10, 9, 8, 7, or 6 locusconversions. A locus conversion of 19GN2390G will otherwise retain thegenetic integrity of 19GN2390G. For example, a locus conversion of19GN2390G can be developed when DNA sequences are introduced throughbackcrossing, with a parent of 19GN2390G utilized as the recurrentparent. Both naturally occurring and transgenic DNA sequences may beintroduced through backcrossing techniques. A backcross conversion mayproduce a plant with a locus conversion in at least one or morebackcrosses, including at least 2 crosses, at least 3 crosses, at least4 crosses, at least 5 crosses and the like. Molecular marker assistedbreeding or selection may be utilized to reduce the number ofbackcrosses necessary to achieve the backcross conversion. For example,a backcross conversion can be made in as few as two backcrosses.

Disease—Sclerotinia

Sclerotinia infects over 100 species of plants, including Brassicaspecies. Sclerotinia sclerotiorum is responsible for over 99% ofSclerotinia disease, while Sclerotinia minor produces less than 1% ofthe disease. Sclerotinia produces sclerotia, irregularly-shaped, darkoverwintering bodies, which can endure in soil for four to five years.The sclerotia can germinate carpogenically or myceliogenically,depending on the environmental conditions and crop canopies. The twotypes of germination cause two distinct types of diseases. Sclerotiathat germinate carpogenically produce apothecia and ascospores thatinfect above-ground tissues, resulting in stem blight, stalk rot, headrot, pod rot, white mold and blossom blight of plants. Sclerotia thatgerminate myceliogenically produce mycelia that infect root tissues,causing crown rot, root rot and basal stalk rot.

Sclerotinia causes Sclerotinia stem rot, also known as white mold, inBrassica, including canola. The disease is favored by moist soilconditions (at least 10 days at or near field capacity) and temperaturesof 15-25° C., prior to and during canola flowering. The spores cannotinfect leaves and stems directly; they must first land on flowers,fallen petals, and pollen on the stems and leaves. The fungal spores usethe flower parts as a food source as they germinate and infect theplant.

The severity of Sclerotinia in Brassica is variable, and is dependent onthe time of infection and climatic conditions, being favored by cooltemperatures between 20 and 25° C., prolonged precipitation and relativehumidities of greater than 80%. Losses ranging from 5 to 100% have beenreported for individual fields. Sclerotinia can cause heavy losses inwet swaths and result in economic losses of millions of dollars.

The symptoms of Sclerotinia infection usually develop several weeksafter flowering begins. The infections often develop where the leaf andthe stem join. Infected stems appear bleached and tend to shred. Hardblack fungal sclerotia develop within the infected stems, branches, orpods. Plants infected at flowering produce little or no seed. Plantswith girdled stems wilt and ripen prematurely. Severely infected cropsfrequently lodge, shatter at swathing, and make swathing more timeconsuming. Infections can occur in all above-ground plant parts,especially in dense or lodged stands, where plant-to-plant contactfacilitates the spread of infection. New sclerotia carry the diseaseover to the next season.

Conventional methods for control of Sclerotinia diseases include (a)chemical control (fungicides such as benomyl, vinclozolin, iprodione,azoxystrobin, prothioconazole, boscalid), (b) disease resistance (suchas partial resistance and breeding for favorable morphologies such asincreased standability, reduced petal retention, branching (less compactand/or higher), and early leaf abscission) and (c) cultural control.

Methods for generating Sclerotinia resistant Brassica plants usinginbred line 19GN2390G are provided, including crossing with one or morelines containing one or more genes contributing to Sclerotiniaresistance and selecting for resistance. In some embodiments, 19GN2390Gcan be modified to have resistance to Sclerotinia.

Homogenous and reproducible canola hybrids are useful for the productionof a commercial crop on a reliable basis. There are a number ofanalytical methods available to determine the phenotypic stability of acanola hybrid.

Phenotypic characteristics most often are observed for traits associatedwith seed yield, seed oil content, seed protein content, fatty acidcomposition of oil, glucosinolate content of meal, growth habit, lodgingresistance, plant height, shatter resistance, etc. A plant's genotypecan be used to identify plants of the same variety or a related variety.For example, the genotype can be used to determine the pedigree of aplant. There are many laboratory-based techniques available for theanalysis, comparison and characterization of plant genotype; among theseare Isozyme Electrophoresis, Restriction Fragment Length Polymorphisms(RFLPs), Randomly Amplified Polymorphic DNAs (RAPDs), Arbitrarily PrimedPolymerase Chain Reaction (AP-PCR), DNA Amplification Fingerprinting(DAF), Sequence Characterized Amplified Regions (SCARs), AmplifiedFragment Length Polymorphisms (AFLPs), Simple Sequence Repeats (SSRs)which are also referred to as Microsatellites, and Single NucleotidePolymorphisms (SNPs).

Particular markers used for these purposes may include any type ofmarker and marker profile which provides a means of distinguishingvarieties. A genetic marker profile can be used, for example, toidentify plants of the same variety or related varieties or to determineor validate a pedigree. In addition to being used for identification ofcanola variety 19GN2390G and its plant parts, the genetic marker profileis also useful in developing a locus conversion of 19GN2390G.

Methods of isolating nucleic acids from 19GN2390G and methods forperforming genetic marker profiles using SNP and SSR polymorphisms areprovided. SNPs are genetic markers based on a polymorphism in a singlenucleotide. A marker system based on SNPs can be highly informative inlinkage analysis relative to other marker systems in that multiplealleles may be present.

A method comprising isolating nucleic acids, such as DNA, from a plant,a plant part, plant cell or a seed of the canola varieties disclosedherein is provided. The method can include mechanical, electrical and/orchemical disruption of the plant, plant part, plant cell or seed,contacting the disrupted plant, plant part, plant cell or seed with abuffer or solvent, to produce a solution or suspension comprisingnucleic acids, optionally contacting the nucleic acids with aprecipitating agent to precipitate the nucleic acids, optionallyextracting the nucleic acids, and optionally separating the nucleicacids such as by centrifugation or by binding to beads or a column, withsubsequent elution, or a combination thereof. If DNA is being isolated,an RNase can be included in one or more of the method steps. The nucleicacids isolated can comprise all or substantially all of the genomic DNAsequence, all or substantially all of the chromosomal DNA sequence orall or substantially all of the coding sequences (cDNA) of the plant,plant part, or plant cell from which they were isolated. The nucleicacids isolated can comprise all, substantially all, or essentially allof the genetic complement of the plant. The nucleic acids isolated cancomprise a genetic complement of the canola variety. The amount and typeof nucleic acids isolated may be sufficient to permit whole genomesequencing of the plant from which they were isolated or chromosomalmarker analysis of the plant from which they were isolated.

The methods can be used to produce nucleic acids from the plant, plantpart, seed or cell, which nucleic acids can be, for example, analyzed toproduce data. The data can be recorded. The nucleic acids from thedisrupted cell, the disrupted plant, plant part, plant cell or seed orthe nucleic acids following isolation or separation can be contactedwith primers and nucleotide bases, and/or a polymerase to facilitate PCRsequencing or marker analysis of the nucleic acids. In some examples,the nucleic acids produced can be sequenced or contacted with markers toproduce a genetic profile, a molecular profile, a marker profile, ahaplotype, or any combination thereof. In some examples, the geneticprofile or nucleotide sequence is recorded on a computer readablemedium. In other examples, the methods may further comprise using thenucleic acids produced from plants, plant parts, plant cells or seeds ina plant breeding program, for example in making crosses, selectionand/or advancement decisions in a breeding program. Crossing includesany type of plant breeding crossing method, including but not limited tocrosses to produce hybrids, outcrossing, selfing, backcrossing, locusconversion, introgression and the like. Favorable genotypes and ormarker profiles, optionally associated with a trait of interest, may beidentified by one or more methodologies. In some examples one or moremarkers are used, including but not limited to restriction fragmentlength polymorphism (RFLP), random amplified polymorphic DNA (RAPD),amplified fragment length polymorphism (AFLP), inter-simple sequencerepeats (ISSRs), sequence characterized regions (SCARs), sequence tagsites (STSs), cleaved amplified polymorphic sequences (CAPS),microsatellites, simple sequence repeats (SSRs), expressed sequence tags(ESTs), single nucleotide polymorphisms (SNPs), and diversity arraystechnology (DArT), sequencing, and the like. In some methods, a targetnucleic acid is amplified prior to hybridization with a probe. In othercases, the target nucleic acid is not amplified prior to hybridization,such as methods using molecular inversion probes. In some examples, thegenotype related to a specific trait is monitored, while in otherexamples, a genome-wide evaluation including but not limited to one ormore of marker panels, library screens, association studies,microarrays, gene chips, expression studies, or sequencing such aswhole-genome resequencing and genotyping-by-sequencing (GBS) may beused. In some examples, no target-specific probe is needed, for exampleby using sequencing technologies, including but not limited tonext-generation sequencing methods (see, for example, Metzker (2010) NatRev Genet 11:31-46; and, Egan et al. (2012) Am J Bot 99:175-185) such assequencing by synthesis (e.g., Roche 454 pyrosequencing, Illumina GenomeAnalyzer, and Ion Torrent PGM or Proton systems), sequencing by ligation(e.g., SOLiD from Applied Biosystems, and Polnator system from AzcoBiotech), and single molecule sequencing (SMS or third-generationsequencing) which eliminate template amplification (e.g., Helicossystem, and PacBio RS system from Pacific BioSciences). Furthertechnologies include optical sequencing systems (e.g., Starlight fromLife Technologies), and nanopore sequencing (e.g., GridION from OxfordNanopore Technologies). Each of these may be coupled with one or moreenrichment strategies for organellar or nuclear genomes in order toreduce the complexity of the genome under investigation via PCR,hybridization, restriction enzyme (see, e.g., Elshire et al. (2011) PLoSONE 6:e19379), and expression methods. In some examples, no referencegenome sequence is needed in order to complete the analysis. 19GN2390Gand its plant parts can be identified through a molecular markerprofile. Such plant parts may be either diploid or haploid. Alsoencompassed and described are plants and plant parts substantiallybenefiting from the use of variety 19GN2390G in their development, suchas variety 19GN2390G comprising a locus conversion or single locusconversion.

In particular, a process of making seed substantially retaining themolecular marker profile of canola variety 19GN2390G is provided.Obtaining a seed of hybrid canola variety 19GN2390G further comprising alocus conversion, wherein representative seed is produced by crossing afirst plant of variety G00012 or a locus conversion thereof with asecond plant of variety N00655 or a locus conversion thereof, andwherein representative seed of said varieties G00012 and N00655 havebeen deposited and wherein said canola variety 19GN2390G furthercomprising a locus conversion has 92%, 93%, 94%, 95%, 96%, 97%, 98% or99% of the same polymorphisms for molecular markers as the plant orplant part of canola variety 19GN2390G. The type of molecular markerused in the molecular profile can be but is not limited to SingleNucleotide Polymorphisms, SNPs. A process of making seed retainingessentially the same phenotypic, physiological, morphological or anycombination thereof characteristics of canola variety 19GN2390G is alsocontemplated. Obtaining a seed of hybrid canola variety 19GN2390Gfurther comprising a locus conversion, wherein representative seed isproduced by crossing a first plant of variety G00012 or a locusconversion thereof with a second plant of variety N00655 or a locusconversion thereof, and wherein representative seed of said varietiesG00012 and N00655 have been deposited and wherein said canola variety19GN2390G further comprising a locus conversion has essentially the samemorphological characteristics as canola variety 19GN2390G when grown inthe same environmental conditions. The same environmental conditions maybe, but is not limited to, a side-by-side comparison. Thecharacteristics can be or include, for example, those listed in Table 1.The comparison can be made using any number of professionally acceptedexperimental designs and statistical analysis.

Hybrid 19GN2390G can be advantageously used in accordance with thebreeding methods described herein and those known in the art to producehybrids and other progeny plants retaining desired trait combinations of19GN2390G. Disclosed are methods for producing a canola plant bycrossing a first parent canola plant with a second parent canola plantwherein either the first or second parent canola plant is canola variety19GN2390G. Further, both first and second parent canola plants can comefrom the canola variety 19GN2390G. Either the first or the second parentplant may be male sterile. Methods for producing subsequent generationsof seed from seed of variety 19GN2390G, harvesting the subsequentgeneration of seed; and planting the subsequent generation of seed areprovided.

Still further provided are methods for producing a 19GN2390G-derivedcanola plant by crossing canola variety 19GN2390G with a second canolaplant and growing the progeny seed, and repeating the crossing andgrowing steps with the canola 19GN2390G-derived plant from at least 1, 2or 3 times and less than 7, 6, 5, 4, 3 or 2 times. Thus, any suchmethods using the canola variety 19GN2390G are part of this discovery:open pollination, selfing, backcrosses, hybrid production, crosses topopulations, and the like. All plants produced using canola variety19GN2390G as a parent are within the scope of this discovery, includingplants derived from canola variety 19GN2390G. This includes canola linesderived from 19GN2390G which include components for either malesterility or for restoration of fertility. Advantageously, the canolavariety is used in crosses with other, different, canola plants toproduce first generation (F₁) canola hybrid seeds and plants withsuperior characteristics.

The discovery also includes a single-gene locus conversion or a singlelocus conversion of 19GN2390G. A single locus conversion occurs when DNAsequences are introduced or modified through traditional breedingtechniques, such as backcrossing or through transformation. DNAsequences, whether naturally occurring, modified as disclosed herein, ortransgenes, may be introduced using traditional breeding techniques.Desired traits transferred through this process include, but are notlimited to, fertility restoration, fatty acid profile modification,other nutritional enhancements, industrial enhancements, diseaseresistance, insect resistance, herbicide resistance and yieldenhancements. The trait of interest is transferred from the donor parentto the recurrent parent, in this case, the canola plant disclosedherein. Single-gene traits may result from the transfer of either adominant allele or a recessive allele. Selection of progeny containingthe trait of interest is done by direct selection for a trait associatedwith a dominant allele. Selection of progeny for a trait that istransferred via a recessive allele will require growing and selfing thefirst backcross to determine which plants carry the recessive alleles.Recessive traits may require additional progeny testing in successivebackcross generations to determine the presence of the gene of interest.

It should be understood that the canola varieties disclosed herein,through routine manipulation by cytoplasmic genes, nuclear genes, orother factors, can be produced in a male-sterile or restorer form.Canola variety 19GN2390G can be manipulated to be male sterile by any ofa number of methods known in the art, including by the use of mechanicalmethods, chemical methods, self-incompatibility (SI), cytoplasmic malesterility (CMS) (either Ogura or another system), or nuclear malesterility (NMS). The term “manipulated to be male sterile” refers to theuse of any available techniques to produce a male sterile version ofcanola variety 19GN2390G. The male sterility may be either partial orcomplete male sterility. Also disclosed are seed and plants produced bythe use of Canola variety 19GN2390G. Canola variety 19GN2390G can alsofurther comprise a component for fertility restoration of a male sterileplant, such as an Rf restorer gene. In this case, canola variety19GN2390G could then be used as the male plant in seed production.

Also provided is the use of 19GN2390G in tissue culture. As used herein,the term plant includes plant protoplasts, plant cell tissue culturesfrom which canola plants can be regenerated, plant calli, plant clumps,and plant cells that are intact in plants or parts of plants, such asembryos, pollen, ovules, seeds, flowers, kernels, ears, cobs, leaves,husks, stalks, roots, root tips, anthers, silk and the like.

The utility of canola variety 19GN2390G also extends to crosses withother species. Commonly, suitable species include those of the familyBrassicae.

The advent of new molecular biological techniques has allowed theisolation and characterization of genetic elements with specificfunctions, such as encoding specific protein products. Any DNAsequences, whether from a different species or from the same speciesthat are inserted into the genome using transformation are referred toherein collectively as “transgenes”. Transformed versions of the claimedcanola variety 19GN2390G are provided in which transgenes are inserted,introgressed or achieved through genetic modification of nativesequences.

Numerous methods for plant transformation have been developed, includingbiological and physical plant transformation protocols. In addition,expression vectors and in vitro culture methods for plant cell or tissuetransformation and regeneration of plants are available.

In general, methods to transform, modify, edit or alter plant endogenousgenomic DNA include altering the plant native DNA sequence or apre-existing transgenic sequence including regulatory elements, codingand non-coding sequences. These methods can be used, for example, totarget nucleic acids to pre-engineered target recognition sequences inthe genome. Such pre-engineered target sequences may be introduced bygenome editing or modification. As an example, a genetically modifiedplant variety is generated using “custom” or engineered endonucleasessuch as meganucleases produced to modify plant genomes (see e.g., WO2009/114321; Gao et al. (2010) Plant Journal 1:176-187). Anothersite-directed engineering method is through the use of zinc fingerdomain recognition coupled with the restriction properties ofrestriction enzyme. See e.g., Urnov, et al., (2010) Nat Rev Genet.11(9):636-46; Shukla, et al., (2009) Nature 459 (7245):437-41. Atranscription activator-like (TAL) effector-DNA modifying enzyme (TALEor TALEN) is also used to engineer changes in plant genome. See e.g.,US20110145940, Cermak et al., (2011) Nucleic Acids Res. 39(12) and Bochet al., (2009), Science 326(5959): 1509-12. Site-specific modificationof plant genomes can also be performed using the bacterial type IICRISPR (clustered regularly interspaced short palindromic repeats)/Cas(CRISPR-associated) system. See e.g., Belhaj et al., (2013), PlantMethods 9: 39; The Cas9/guide RNA-based system allows targeted cleavageof genomic DNA guided by a customizable small noncoding RNA in plants(see e.g., WO 2015026883A1).

Plant transformation methods may involve the construction of anexpression vector. Such a vector comprises a DNA sequence that containsa gene under the control of or operatively linked to a regulatoryelement, for example a promoter. The vector may contain one or moregenes and one or more regulatory elements.

One or more traits which may be modified or introduced in the plants andmethods disclosed herein include male sterility, herbicide resistance,insect resistance, pest resistance, modified fatty acid metabolism,modified carbohydrate metabolism, modified seed yield, modified oilpercent, modified protein percent, modified lodging resistance andmodified resistance to bacterial disease, fungal disease or viraldisease.

A genetic trait which has been engineered or modified into a particularcanola plant using transformation techniques could be moved into anotherline using traditional breeding techniques that are well known in theplant breeding arts. For example, a backcrossing approach could be usedto move a transgene from a transformed canola plant to an elite inbredline and the resulting progeny would comprise a transgene. Also, if aninbred line was used for the transformation then the transgenic plantscould be crossed to a different line in order to produce a transgenichybrid canola plant. As used herein, “crossing” can refer to a simple Xby Y cross, or the process of backcrossing, depending on the context.Various genetic elements can be introduced into the plant genome usingtransformation. These elements include but are not limited to genes;coding sequences; inducible, constitutive, and tissue specificpromoters; enhancing sequences; and signal and targeting sequences.

Transgenic and modified plants described herein can produce a foreign ormodified protein in commercial quantities. Thus, techniques for theselection and propagation of transformed plants, which are wellunderstood in the art, may yield a plurality of transgenic or modifiedplants which are harvested in a conventional manner, and a foreign ormodified protein then can be extracted from a tissue of interest or fromtotal biomass.

A genetic map can be generated, primarily via conventional RestrictionFragment Length Polymorphisms (RFLP), Polymerase Chain Reaction (PCR)analysis, Simple Sequence Repeats (SSR), and Single NucleotidePolymorphisms (SNPs), which identifies the approximate chromosomallocation of the integrated DNA molecule coding for the foreign protein.Map information concerning chromosomal location is useful forproprietary protection of a subject transgenic plant. If unauthorizedpropagation is undertaken and crosses made with other germplasm, the mapof the integration region can be compared to similar maps for suspectplants, to determine if the latter have a common parentage with thesubject plant. Map comparisons would involve hybridizations, RFLP, PCR,SSR, SNP, and sequencing, all of which are conventional techniques.

Likewise, by means of the present discovery, plants can be geneticallyengineered to express various phenotypes of agronomic interest.Exemplary transgenes implicated in this regard include, but are notlimited to, those categorized below.
